The “American Top 40″ host is suffering from a debilitating condition that has left him barely able to speak.

Meanwhile, family members are engaged in a bitter feud for control over his medical care. Emotions boiled over last Sunday, when Jean Kasem, his wife of 34 years, threw hamburger meat at his daughter Kerri from his first marriage, just before the radio personality was taken to the hospital.

The bizarre incident was the latest in a long battle. Last month, after Kasem disappeared from his care facility in Santa Monica, Calif., his children reported him missing. Authorities later tracked him down to a friend’s home in Seattle where Jean told police they were on vacation.
